         6 . The communication apparatus according to  claim 1 ,
 wherein the determination unit determines that the same apparatus has been detected using the first wireless frame and the second wireless frame, based on sources of frames included in each of the first wireless frame and the second wireless frame having the same device name.   
     
     
         7 . The communication apparatus according to  claim 6 ,
 wherein the output unit outputs a screen including a device name of the other communication apparatus detected through the first detection and the second detection.   
     
     
         8 . The communication apparatus according to  claim 1 ,
 wherein the determination unit determines that the same apparatus has been detected using the first wireless frame and the second wireless frame, based on service names provided by a device that is a source of frames included in each of the first wireless frame and the second wireless frame being the same service name.   
     
     
         9 . The communication apparatus according to  claim 8 ,
 wherein the output unit outputs a screen including a service name provided by the other communication apparatus detected through the first detection and the second detection.   
     
     
         10 . The communication apparatus according to  claim 1 ,
 wherein the determination unit determines that the same apparatus has been detected using the first wireless frame and the second wireless frame, based on sources of frames included in each of the first wireless frame and the second wireless frame having the same UUID.   
     
     
         11 . The communication apparatus according to  claim 10 ,
 wherein the output unit outputs a screen including a UUID of the other communication apparatus detected through the first detection and the second detection.   
     
     
         12 . A control method executed by a communication apparatus that communicates a wireless frame compliant with a Wi-Fi Direct (WFD) standard, the control method comprising:
 performing a first detection of an other communication apparatus according to a first method of searching for a partner apparatus for communication using a first wireless frame, the first wireless frame being defined by the WFD standard;   performing a second detection of an other communication apparatus according to a second method of searching for the partner apparatus using a second wireless frame, the second wireless frame being defined by the WFD standard and not being used in the first method;   determining whether a same apparatus has been detected in the first detection and the second detection by analyzing the first wireless frame and the second wireless frame; and   outputting information about the other communication apparatus detected by the first detection and the second detection, the information indicating the apparatus as a single apparatus when the same apparatus has been detected in the first detection and the second detection.
